Claiiifs.

The invention described herein, if patented, may be manufactured andused by the Government for governmental purposes without the payment tome of any royalty thereon.

This invention relates to arutility item yfor the home and comprises astool which may belreadily converted into a ladder or a high chair asoccasion may arise.

-A primar-y object of thedi'n'vention resides in the provision of apiece of furniture as justmcntioned in whichthe several parts areneatlvyfand compactly arranged and yet which may be readily and simplyoperated, with no particular skill, to convert the device from any oneto the other of the several articles mentioned.

Other objects and advantages of the invention will be apparent from thefollowing description when taken in connection with the accompanyingdrawings, in which,

Figure 1 is a front elevational view of the device when set up as a highchair;

Figure 2 is a side elevational view of the arrangement shown in Figurel, with the folded back shown in dotted outline;

Figure 3 is a fragmentary rear elevational View of the arrangement ofFigures 1 and 2; and

Figure 4 is a similar View of the device arranged as a stool andstepladder.

In the present embodiment of the invention, the stool is provided withfour legs I-I which are inclined upwardly as indicated in Figures 1 and2 and provided with cross braces 2 for imparting rigidity to the device,and with ladder rungs 3 so that it may be employed as a ladder from timeto time as desired.

'Ihe legs l, which may be made of aluminum tubing, are of hollowconstruction and open at their upper ends to provide for adjustablysupporting the arms of the high chair construction, as will appearhereinafter.

The seat for the chair or stool may be formed of suitable plywood,plastics, or other material and is indicated by the numeral 4. This seatis provided with a number of apertures 5 corresponding to the number oflegs forming the stool and so situated as to register with the openupper ends of the legs I.

The arms which are to be used when the device is converted into a highchair are indicated by the numeral 6 and comprise inverted U-shapedmembers of aluminum tubing. The legs 6 of these arms, it will be noted,are spaced apart a distance corresponding to the distance between theupper ends of the front and rear legs so that these depending portionswill register with the 2 open illpveif` ends .of the legs land'sli'dably received in the apertures 5 yof the seat portion 4 and theupper ends of the legs themselves. Each leg is provided adjacent theopen upper end thereof with a set screw ,1 adaptedjto cooperate with.that 4portion o'f the leg Si which -is situated within the open`upperjend of the particu-lar leg 4l. It will be apparent, therefore,thatby loosening n the set screws 'l Ythe arms may be lcompletelydepressed as shown in Figure 4 when thedevice isl to be used as a stool,or may be extended vertically as `shown in Figures 1,2, 'and'B andlocked in this extended position by turning down the set screws 'I so asto lock the arms 6 against vertical movement.

The back member of the high chair is composed of an inverted U-shapedframe 8 of aluminum tubing or the like which may be provided with theusual covering to complete the back formation. The lower ends of theinverted U-shaped frame 8 are hingedly connected to the back edge of theseat 4 by means of a pair of hinge pins 9 and the arrangement is suchthat the back may be swung upwardly into its operative position as shownin Figures 1 to 3, inclusive, or swung downwardly to inoperativeposition as shown in full lines in Figure 4 and dotted lines in Figure2. When in this latter position, the back member may be releasablysecured against movement by means of a clamp l0. Also, it is to be notedthat the back member 8 is provided with slide bolts ll adapted tocooperated with apertures l2 formed in the arms 6 so that when the boltsare moved into cooperative relation with the apertures l2 the backmember is securely locked in its erect and operative position.

A tray I3, provided with attaching clamps l, may be provided anddetachably supported on the arms 6, the clamps being so arranged as tosupport the tray I3 in proper relation to the occupant of the highchair. When this tray is not in use, it may be stored away under theseat portion 4 by sliding the same between clips I5 and the bottom ofthe chair to which they are attached.

With the foregoing arrangement, it will be apparent that this compositepiece of furniture may be used as a stepladder, at any time, due to theinclination of the legs l, and may be readily converted into either astool or a high chair by simply operating the set screws l and bolts l lso as to raise or lower the chair arms 6 and swing the back either intoerect and operative positionV or into depending an inoperative positionas the case may be. Moreover, it is to be noted that the structure iscomposed of few parts, of simple and inexpensive construction, butnevertheless provides a sturdy and durable high chair, stool, andstepladder.

I claim: 1. A combined stool and high chair comprising a plurality oflegs and braces therefor, a seat portion permanently secured to the topsof the legs, a back member hingedly connected to the seat portion, apair of vertically slidable arms mounted on the stool, and releasableconnection between said back and arms.

2. A combined stool and high chair comprising a plurality of legs, aseat portion permanently secured to the tops of the legs, a back memberhingedly connected to the seat portion, a pair of vertically slidablearms adjustably mounted on the stool, means for securing said arms inadjusted positions, and a releasable connection between said back andarms.

3. A combined stool and high chair comprising a plurality of legs, aseat portion permanently secured to the tops of the legs, a back memberhingedly connected to the seat member, a pair of inverted U-shaped armsmounted on the stool for vertical adjustment, set screws for securingsaid arms in adjusted positions, and a slidably-mounted bolt forreleasably locking the hinged back member with respect to said arms.

4. A combined stool and high chair comprising a plurality of legs, aseat portion permanently secured to the legs, a back member hingedlyconnected to the seat portion and adapted to be moved into erectoperative position or into a depending and inoperative position, meansfor releasably maintaining the back member in inoperative position, apair of vertically adjustable arms mounted on the stool, and areleasable connection between the arms and back for supporting the backin its erect and operative position.

5. A combined stool, ladder and high chair comprising a plurality ofupwardly inclined legs, a seat portion and ladder rungs permanentlysecured to said legs, a. back member hngedly connected to the seatportion, a pair of vertically adjustable arms mounted on the stool,means for securing the arms in adjusted positions. and a releasableconnection between said back and arms.
